Small rocks can be annoying. They get in the way when you plant tulips, clog up your lawnmower, and your dog keeps burying and unearthing the same pesky pebble. But large rocks — really big rocks — make a bold, natural statement in landscaping that small stones just can’t compete with.
Wondering how to use large rocks in landscaping for your commercial property? From eye-catching focal points to heavy-duty retaining walls, there are plenty of ways to integrate big rocks into your landscape design — and plenty of reasons to do it.
We sat down with Paul Weaver, construction branch manager at Level Green Landscaping, to get his expert take on where these massive beauties come from, why they’re a smart landscaping choice, and how to use them.
“Large, natural boulders are beautiful,” Paul says. “They come in a variety of colors, from purples to browns to grays.”
They also:
Weaver recommends pairing large rocks with mossy plants, creeping ground covers, and native wildflowers to create natural-looking displays that feel like they’ve always been there.
Ready to go big? Here are five practical, visually striking ways to use large rocks and boulders in your commercial landscape design:
Instead of traditional features like statues or shrubs, boulders can serve as living sculptures — especially when surrounded by native or ornamental plantings.
When thoughtfully placed, they can:
They’re a fantastic alternative for office parks, municipal buildings, or mixed-use retail properties that want a low-maintenance, natural aesthetic.
“These boulders are extremely heavy,” Weaver says. “Once they're put in place, they're there forever. That makes them excellent for retaining walls. They’re stronger than any engineered material you can buy.”
You’ve likely seen boulder walls along highways, holding hills in place and preventing landslides. But they’re also great for:
“We have clients who use them to hold their whole property up on one side,” Weaver says.
As stormwater regulations become stricter, more municipalities are encouraging the use of bioretention ponds to filter rainwater before it returns to the groundwater supply.
“Large, natural rocks add beauty and interest to the pond’s landscaping,” Paul says.
Boulders help:
It’s a functional, attractive way to comply with local codes and enhance your landscape.
We’ve all seen it: cars creeping over curbs, tires flattening carefully planted beds.
“We do a lot of shopping mall renovations, where cars like to drive over our plant beds,” Weaver says. “We often install large rocks on the corners to keep the cars off.”
Strategically placed boulders are a natural alternative to unsightly bollards or fencing — ideal for:
Large rocks aren’t just for looks — they can also be used as natural steps, casual seating areas, or even as part of custom water features.
“We've had customers say they want a boulder the size of a Volkswagen,” Weaver says. “Well, then you wouldn't be able to see half of their building.”
The right sizing and placement matters. That’s where professional planning comes in.
“Using these large rocks is surprisingly easy,” Weaver says. “It's not that expensive — they can fit in any budget — and it's relatively simple to place them, with help from some big machines.”
Each boulder typically weighs between 500 and 1,000 lbs. They’re delivered directly to job sites and moved into place using:
Once set, “they’re not going anywhere,” Paul adds.
Because boulders are heavy and permanent, planning is crucial.
“Almost every retaining wall we do with large boulders starts with a drawing by an engineering firm,” Paul says. “They give us a drawing based on the boulder’s height, depth, and placement. We get a set of plans and we install based on that.”
On smaller projects, Level Green’s team handles calculations in-house. Either way, drainage is a key concern.
“You don't want water to wash away the dirt that holds the boulder there,” he says. “We install the proper drainage as we install the rocks.”
Here’s a fun fact: Most landscaping boulders used on the East Coast come from Meshoppen, Pennsylvania.
Four or five companies in the area blast massive chunks from the mountains, then break them into landscape-ready boulders and ship them to wholesalers and retailers via 18-wheelers.
Are the mountains going to run out of rock?
“Not in our lifetime,” Weaver laughs.
